I would control what you could in terms of what you have in the house. You can’t control what she has when she isn’t with you (at school for ex), but you can limit what is in the house. We honestly don’t have junk in the house often, because I personally don’t want it around. My husband has no willpower, so I don’t buy stuff that he will inhale, we, eat in one sitting. It is also more fun to buy something for a treat once in awhile, because I want her to learn moderation. And if we do buy something, its a smaller version of a treat, for ex, a pint of ice cream to share with family, not a half gallon. Believe it or not, some fruits are better to have around than others. I remember a nutritionist compared grapes to a snickers bar! Buy fruits that are not as high in Sugar. I have no idea what kind of drinks are in your house, but juice and sodas are evils also. Buy bubbly water to ease the soda craving maybe? For us, bubbly waters are our soda treats.
